Product Summary

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the moving parts of the bearing. There are several common designs of ball bearing, each offering various trade-offs. They can be made from many different materials, including: stainless steel, chrome steel, and ceramic. A hybrid ball bearing is a bearing with ceramic balls and races of metal.

A Hybrid Ball Bearing is a precision bearing in which one or all of its components are made of ceramic elements from silicon nitride. Silicon nitride is a highly processed silica and ceramic material, similar to the heat absorbing, highly resilient tiles on the Space Shuttle. These tiles are used to line the heat shield of the Space Shuttle, as they protect it from the 2500 plus degrees F. extremes of re-entry into the earth's atmosphere. The use of Ceramics for bearing components results in a far superior product over traditional all steel ball bearings.
